Re:the rings

I'm sorry to hear that you've run into this, as this is a known issue with this game that we're currently working with the developers on in hopes of getting a fix. We'll be sure to post something in the forums if we receive any updates!

In the meantime, according to the comments in the "Miner's rings" thread, there is a workaround for this.

All you need to do is re-start the game with a new player profile, and this time wait until you have collected all 5 rings before putting them on the skeleton.
